General Description
AP1580 consists of step-down switching regulator with PWM control.
These devices include a reference voltage source, oscillation circuit,
error amplifier and internal NMOS.
AP1580 provides low-ripple power, high efficiency and excellent
transient characteristics. The PWM control circuit is able to vary the
duty ratio linearly from 0 up to 90%. An enable function, an over
current protect function and a short circuit protect function are built
inside, and when OCP or SCP happens, the operation frequency
will be reduced from 300 KHz to 30 KHz. Also, an internal
compensation block is built to minimize external component count.
With built-in power NMOS, a step-down switching regulator is easy
to be built by adding a coil, capacitors and a diode.
The high efficiency (>90%), low standby current, high input
voltage (40V) and output current (3A) combining with small
SOP-8L package give AP1580 unprecedented advantage in high
power system applications.
